Specification of Letters Patent.

Patented Aug. 8, 1916.

Original application filed November 7, 1905, Serial No. 286,229. Divided and this application filed November To all whom it may concern:

Be it known that I, CHASE C. REED, a citizen of the United States, residing at T0 ledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Rotary Plowing-Cylinders, of which the following is a specification.

My invention relates to plowing machines of the class wherein a motor driven rotary plow or cutter is mounted on a suitable wheeled carriage or plow frame, and relates particularly to the construction of the rotary cutting cylinder or digging element of such a machine.

In my prior application for patent, filed November 7th, 1905, Serial No. 286,229, of which the present application is a division, I have fully described a plowing machine of which the rotary cutting cylinder which forms the subject matter of the present application is a part, and it will therefore be unnecessary to herein fully describe the particular arrangement and construction of such machine.

The object of the present invention is the provision of a rotary plow adapted to thoroughly dig and pulverize the soil, which shall be strong, durable and eliicient, and in general be well adapted and suited to accomplish the ends in View.

The novelty and essential elements of my invention are more particularly pointed out in the appended claims.

In the drawings Figure 1 is a side View of a portion of a plowing machine equipped with my new rotary plow cylinder; Fig. 2 is an end view of the cylinder alone; Fig. 3 is a side view of one end of the cylinder, and Fig. 4 a view of one of the blades forming the cutting element of the cylinder, and a backing plate used in connection with such blades.

The same letters of reference are used to indicate the same parts in the several figures of the drawing.

For an understanding of my present invention it will suffice to explain that my rotary plow is rotatably mounted in a plow frame 1 which at its forward end is pivoted to a second frame 2, such second frame in the present instance being a supplemental frame supported at its rear end by ground wheels ee -mine. 60,516.

or gage wheels 3 and pivoted at its front end to the main frame of the machine. This main frame is mounted upon wheels arranged to be driven through a suitable motor, as the engine t mounted on such frames, to propel the machine. The plow frame 1 in which the rotary plow is mounted is adapted to be raised and lowered with respect to the gage wheels 3, to adjust the depth of cut, by suitable means, as for instance a pair of cables 5 fastened at their rear ends to the read end of the frame 1 and extending over pulleys supported on the frame 2, the forward ends of these cables be ing adapted to be drawn up or slackened by a suitable Windlass device.

In the plow frame 1, at points interme diate the length of its side bars, is rotatably mounted a transverse rod or shaft 6 on which is mounted or secured the plow. As illustrated more particularly in Figs. 1, 2 and 3 this plow comprises, in the present instance, a cylinder or shell 7 preferably of metal and of suitable diameter and length and provided at its ends and also intermediate its length with a series of spiders 8 of a number which will vary with the length of the cylinder, whereby such cylinder or shell will be firmly supported or braced along its entire length, it being understood that the shaft 6 passes centrally through the cylinder and through said spiders. Projecting laterally from the cylinder is a series of rings 9 of suitable number according to the length of the cylinder and adapted to form points of attachment for the knives or knife blades.

As illustrated clearly in Figs. 2, 3 and 4 there is a series of knives which substantially equal in length the distance between adja cent rings. By preference each knife has a backing or support which not only provides for a suitable means of attachment of the knives and means for supporting the same but also provides a bucket for carrying the plowed soil upwardly and discharging it at the rear of the machine. As shown and referring to the preferred construction each knife consists of a blade 10 having rightangled ends 11, which ends extend or lap over adjacent rings, such blade being preferably slightly convexed for the sake of rigidity and to prevent buckling which might posslbly occur in case the knives were straight. The backing of each knife consists of a plate 12 having right-angled ends 13 which fit between adjacent rings.

In practice the knives and their backings are secured to the rings by bolts and in the present instance the same bolts secure the knives and the backing in place by passing through the ends 11 and 13 thereof respectively. As above stated, the knives are slightly convexed which has a tendency to make the cutting surface of the plow irregular but to reduce this consequence to a minimum the knives lap over the rings 9 in the manner already explained and in addition the successive sets of knives are arranged in staggered relationship as clearly indicated in Fig. 8. It will now be seen that even though the knives are convex, the cutting surface is more nearly straight than if the knives were all secured to the inner faces of the rings instead of lapping over them and in addition the cutting surface is caused to extend over the outer edges of the rings, with the result that the cutting surface from end to end of the cylinder is substantially straight and continuous.

It will be understood that the construction of knives herein illustrated is the preferred one, but that variations may be made in the construction without departing from the spirit of my invention. For instance the knife and its backing may be made in a single piece, and again, the backing may be entirely dispensed with, in which event no buckets would be formed for carrying the dirt effectively from the front to the rear of the plow.

It will be understood that by suitable operating connections as, for instance, a pair of sprocket chains 1A connected with the engine 4 and coope ating with sprocket wheels 15 secured to the shaft of the plow cylinder, the plow cylinder is driven so that the blades 1.0 out forwardly-that is, in the direction of movement of the machine,and the soil is carried upwardly around the axis of the cylinder and discharged at the rear as the machine travels forward. By preference a curved shield 40 secured to the plow frame 1, is arranged over and adapted to partially envelop the plow.

I claim:

1. A plow comprising a rotatable plowing cylinder, a series of rings along the length thereof, and separate series of knife blades along the length of the cylinder to form substantially a continuous cutting surface, the blades of each series extending over two adjacent rings and secured to the outer sides thereof.

2. A plow comprising a rotatable plowing Copies of this patent may be obtained for cylinder, a series of end and intermediate rings along the length thereof, a series of longitudinally-disposed knife blades whose opposite ends extend over to adjacent rings and are secured to the outer sides thereof, and a series of plates secured to the inner sides of such rings to cooperate with said blades.

3. A plow comprising a rotatable plowing cylinder, a series of end and intermediate rings along the length thereof, a series of longitudinally-disposed knife blades having a convex cutting edge, and a corresponding series of plates having similar convex edges to support said knife blades.

4. A plow comprising a rotatable plowing cylinder consisting of an imperforate shell, a series of end and intermediate rings along the length thereof, and series of knife blades secured to such rings.

5. A plow comprising a rotatable plowing cylinder consisting of an imperforate shell, a series of end and intermediate rings along the length thereof, and a series of knife blades secured to the rings and arranged in staggered relationship.

6. A plow comprising a rotatable plowing cylinder consisting of an imperforate shell, a series of end and intermediate rings along the length thereof, and a series of knife blades secured to the rings and of less length than the cylinder, the blades of successive series overlapping each other as to their adjacentends.

7. A plow comprising a rotatable plowing cylinder, a series of rings along the length thereof, a series of knife blades secured to the rings, and a corresponding series of plates cooperating with the knife blades to form buckets.

S. A plow comprising a rotatable cylindrical imperforate shell having a plurality of series of knife blades arranged in bands around said cylinder, the knife blades of the separate series being slightly convex on the1 r cutting edges and being disposed longitudlnally of the cylinder in staggered relation,

9. A plow comprising a rotatable cyl ndrical imperforate shell having a plurahty of end and intermediate rings along 1ts length, and separate series of knife blades slightly convex on their cutting edges and seemed to said rings, the blades of adjacent series extending over and being secured to the ring between such series in staggered relation.
